Granted, "free will" and "choice" are complex topics.

But it's confusing to use a word like "choose" and then immediately say "outside of their direct control".

On reflection, I think the point that you were trying to make was something like:

"Regardless of whether the cause is societal pressure, neurobiology, or personal choices, women are potentially suffering from lower pay."

I liked the article before the conclusion, however.

Lol. Well, perhaps I'll reword the conclusion. I suppose it was a bit confusing. I was arguing that a woman's "choice" could be caused/influenced by societal pressure or neurobiology. And either way, to what extent is this a robust "choice"? Personally, I believe that neurobiology is the cause of all our behavior. However, I think it is still worth bringing up the implications of that line of thought. As I said before, there are neurobiological reasons for racism. Of course, these reasons do not JUSTIFY racism, they merely EXPLAIN it. And so, in my conclusion, I wanted to bring up the issue -- "Although we may be able to explain lower pay, either through neurobiology, societal pressure, or otherwise, this does not necessarily justify it."

Yes, that wording is much better.

Person1: "My house washed away!" Person2: "I have found the cause: it was that hurricane last night. My work here is done; glad I could help; you are very welcome."
